10-Jul-2008 09:31 EDT

The Lee Company’s 250 Zero Leak Chek joins the company’s line of miniature, zero-leak check valves. Available in forward and reverse flow configurations, the 250 uses an elastomeric seat to achieve zero leakage. The remaining components are constructed of stainless steel. Features of the valve include a flow of more than 62 L/min (2.2 ft3/min) at 25 psi (1.7 bar), a diameter of 0.250 in (6.35 mm), and a nominal weight of 3.8 g (0.13 oz). Maximum working pressure is 3000 psi (207 bar). The valve is suitable for use in down-hole oil tools and aerospace applications. Custom variations with higher pressure ratings are also available.
